They were ordained to become church ministers as Pastors in 1996 in a local church in Tsuen Wan and have been ministering to this same congregation for about 30 years now.

Over the years, she has gone on church missions to Mongolia, Sydney, Nepal, India and expedition trips to the Holy Lands: Israel, Greece and Turkey. Wherever she went, she found herself taking up the music ministry and became the church pianist for that church.

Many people at church have asked her to teach them to play piano. Her piano courses are very unique because she was finally willing to share her Unique Piano Method:Color ChordImprovisation Method known as CCI. The CCI method works for all types of music: Gospel, Pop and Standards.

This Piano Method is easy,fun and creative that you learn to play piano not only from music score sheets, but to play chords from fake books and eventually to play by ear. Students all over the world have requested for courses to teach them play standards and popular songs. As a result she developed 3 Great Reharmonization Method courses for them to play from fake books and play by ear. The Dreamy Piano Techniques courses, especially the one on Autumn Leaves is her students favorite. She has a piano website at Learn Piano With Rosa where she continues to offer new courses to her students.
